Detailed Description

Implement CV as a Service authentication support

Is your feature request related to a problem? Please describe.

CVaaS authenticates the user using a token which is different from the on-premise instance of Cloudvision. The authentication mechanism should be changed to support both options.

Todo:

• [x] Create authentication method in module_utils
• [ ] Add trigger to select either on-prem or cvaas
• [ ] Update cv_facts
• [ ] Update cv_configlet
• [ ] Update cv_container
• [ ] Update cv_device
• [ ] Update cv_task
• [ ] Create HOW-TO documentation
• [ ] Run testing against CVaaS instance
• [ ] Validate AVD workflow

cvprac implementation for cvaas:

>>> from cvprac.cvp_client import CvpClient
>>> clnt = CvpClient()
>>> clnt.connect(nodes=['cvaas'], username='', 
                 password='', 
                 is_cvaas=True, 
                 cvaas_token='user token')
>>> result = clnt.api.get_cvp_info()
>>> print result
{u'version': u'cvaas'}
>>>
